Buried deep in the Mojave Desert is one of the biggest and richest deposits of borax on the planet. There, on the rim of our active Borax mine, you will find the Borax Visitor Center: One of the best-kept secrets of the Southern California desert. Built in 1997, the Center tells the story of borax and the local community.
